Please can you add help text here? The main OF_LIVE option has a
helpful explanation. Also there should only be one blank line after
the entry.

The U-Boot proper code in initr_of_live() wraps of_live_build() with
bootstage_start()/bootstage_accum() using BOOTSTAGE_ID_ACCUM_OF_LIVE.
Please can you do the same here for consistency and SPL boot-time
tracking.
